Cuba participates in the GEF-8 Sustainable Cities Integrated Program (SCIP) through the Havana Province metropolitan area, advancing integrated planning and climate-resilient urban development. As one of the Caribbean’s largest and most culturally significant urban regions, Havana faces challenges linked to aging infrastructure, exposure to climate risks, and the need for greener, more efficient urban services. Through SCIP and the GPSC Global Knowledge Platform, Cuba is developing a knowledge and investment framework that supports nature-based solutions, decarbonized infrastructure, circular economy measures, and strengthened urban governance. These efforts aim to mobilize public and private finance for resilient, inclusive urban transformation. Cuba’s engagement provides important learning for the wider GEF network, particularly in adapting coastal cities to climate impacts while preserving cultural heritage and social cohesion.
